我试图在我的Centos 6.0,64位，PHP 5.3.3上安装php-mcrypt。 我使用epel repo rpm -Uvh http://download.fedora.redhat.com/pub/epel/6/x86_64/epel-release-6-5.noarch.rpm ，最后一个。
但是，我运行yum install php-mcrypt我得到一个错误

为什么埃佩尔不给我最后的encryption？ php-mcrypt-5.1.6-5.el5.x86_64不是最新版本的回购…我能做什么？
软件包php-mcrypt.x86_64 0：5.1.6-5.el5将被安装
注意el5 ，这意味着这个包是从EL5回购的。 确保epel-release-6-5.noarch.rpm已经安装成功：
$ rpm -qa | grep epel epel-release-6-5.noarch
和mirrorlist （在/etc/yum.repos.d/epel.repo ）指向正确的path：
[epel] name=Extra Packages for Enterprise Linux 6 - $basearch #baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch failovermethod=priority enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
（ epel-6而不是epel-5 ）
如果有人在将来遇到这个问题，我做了这个：
删除了以前的EPEL安装。 yum remove epel-release
然后安装最新版本的CentOS 6。
$ cd /tmp
$ wget http://mirror-fpt-telecom.fpt.net/centos/6.6/extras/x86_64/Packages/epel-release-6-8.noarch.rpm
$ rpm -ivh epel-release-6-8.noarch.rpm
从那时起，我只是运行yum install php-mcrypt命令并安装好php-mcrypt。
你可以试试这个：
wget http://dag.wieers.com/rpm/packages/libmcrypt/libmcrypt-2.5.7-1.2.el6.rf.x86_64.rpm
wget http://dag.wieers.com/rpm/packages/libmcrypt/libmcrypt-devel-2.5.7-1.2.el6.rf.x86_64.rpm
rpm -Uvh libmcrypt – *。rpm
我用了很长时间没有任何问题。
